How to override an ARMTemplateParametersForFactory.json [Array as value] in GitHub Actions

Question

I already got help from this "You can override the parameters in parameter file by explictly calling it out next to the parameter file. Example : parameters: repo/ARM/azuredeploy.resourcegroup.parameters.json rgName=${{env.RESOURCEGROUP_NAME}} This will override the rgName."

But the problem I got for now is I have Key, Values as this in ARMTemplateParametersForFactory.json

I already override factoryName as this in GitHub Actions

parameters: ./ARM/ARMTemplateParametersForFactory.json factoryName=test001 sta_properties_fqdns=[test002]

The error said:

Validating template... Warning: ERROR: Failed to parse string as JSON: [test002] Error detail: Expecting value: line 1 column 2 (char 1)

Warning: Template validation failed. Creating deployment... Error: ERROR: Failed to parse string as JSON: [test002] Error detail: Expecting value: line 1 column 2 (char 1)

How should I override the Array value in this case

Answer 1

To override an array value in GitHub Actions for the ARMTemplateParametersForFactory.json, you need to ensure the array is formatted correctly as a JSON string. The error you are encountering happens because the array is not properly escaped as a string in the GitHub Actions YAML file.

parameters: ./ARM/ARMTemplateParametersForFactory.json factoryName=test001 sta_properties_fqdns="[\"test002\"]"

In this example, sta_properties_fqdns is being passed as a JSON array with the value ["test002"]. The inner quotes are escaped so that it is recognized as a valid JSON array.

Try this format and it should resolve the parsing error.
